But even the disco was catchy and had decent tunes - not like some of the repetitive dance music that was out by the end of the 80s!

Can't disagree with that, it's just that disco took over so much that that was all some radio stations, which previously were quite varied in their output, ever played. Also, acts like Abba, Rolling Stones, ELO and Rod Stewart released disco tracks with varying degrees of success (Do Ya Think I'm Sexy being a great track, but things like Summer Night City being amongst Abba's worst).

Yeah a lot of these bands DID jump on the disco band-wagon but I must admit I quite like Summer Night City by Abba!
